Fields

anchor: Option<ReceiptProofAnchor>

The Tempo on-chain anchor for that day’s root. Null before the day’s root has been anchored (daily roll-up + anchor happens once per day, the next day).

audit_path: Vec<String>

0x-prefixed sibling hashes proving leaf_hash includes under root_hash. Selective disclosure by construction — never sibling receipts’ identifiers.

citable_id: String

Stable citation id derived from the payload hash (precedent registry, gh#126)

day: NaiveDate

UTC day (YYYY-MM-DD) whose Merkle batch this leaf belongs to

leaf_hash: String

0x-prefixed hash of this receipt’s leaf

leaf_index: i64

This receipt’s zero-based leaf index in that day’s tree

payload_hash: String

0x-prefixed SHA-256 payload hash of the receipt this proof covers

root_hash: String

0x-prefixed root hash of that day’s Merkle tree

schema_version: ReceiptProofSchemaVersion

sigsum: Option<ReceiptProofSigsum>

Sigsum witness-cosigning evidence for that day’s root. Null when no log round-trip happened for that day (for example SIGSUM_LOG_URL unset).

tree_size: i64

Number of leaves in that day’s Merkle tree
